单选题If those "mad moments"— when you can't recall what your friend has told you or where you left your keys—are becoming more frequent, mental exercises and a healthy brain diet may help. Just as bodies require more maintenance with the passing years, so do brains, which scientists now know show signs of aging as early as the 20s and 30s. "Brain aging starts at a very young age, younger than any of us have imagined and these processes continue gradually over the years," said Dr. Gary Small, the director of the Center on Aging at the University of California, Los Angeles. "I'm convinced that it is never too early to get started on a mental or brain-fitness program," he added. In his book, "The Memory Bible," the 51-year-old neuroscientist lists what he refers to as the 10 commandments for keeping the brain young. They include training memory, building skills, minimizing stress, mental exercises, brain food and a healthy lifestyle. It's a game plan for keeping brain cells sparking and neural networks in tip-top shape. "Misplacing your keys a couple of times doesn't mean you should start labeling your cabinets. Memory loss is not an inevitable consequence of aging. Our brains can fight back," he said. Small provides the weapons for a full-scale attack. According to him, simple memory tests give an indication of what you are up against and tools such as look, snap and connect are designed to make sure that important things such as names and dates are never forgotten. "So if you want to learn names and faces, for example, you meet Mrs. Beatty and you notice a distinguishing facial feature, maybe a prominent eyebrow," said Small. "You associate the first thing that comes to mind. I think of the actor Warren Beatty so I create a mental snapshot of Warren Beatty kissing her brow. " Small admits it may sound a bit strange but he says it works. " Mental exercises could be anything from doing crossword puzzles and writing with your left hand if you are right handed or learning a language. It could be anything that is fun that people enjoy doing", he added. He also recommends physical exercise, a low-fat diet and eating foods rich in omega-3 fatty acids, such as fish, walnuts and Brazil nuts, and fruits and vegetables high in antioxidants (抗氧化剂) including blueberries and onions in addition to reducing stress.

单选题American culture has not been immune to cultural influences from outside. The idea of democracy came from the ancient Greeks: the Industrial Revolution started in England: jazz and rock music preserve African rhythms--to pick a few examples. Indeed, many of the things we think of as "100 percent American" came from other cultures. Still, most of the changes in American culture over the last century have come from within, as the result of inventions and discoveries. And change has been dramatic. One hundred years ago the United States was largely a nation of farmers. Many of the things we take for granted today- a high school education, for example, or indoor plumbing—were luxuries then. The moon was a light for lovers, not a site for scientific exploration; genetic engineering (基因工程) was not even a subject for science fiction, much less for laboratory research and corporate investments. The decades following the Second World War, in particular, were characterized by spectacular scientific and technological advances, national self-confidence, optimism, and (for many Americans) prosperity. The American economy was the strongest in the world: more goods were produced and sold, more people were working, and the standard of living was higher than ever before. Polls (民意调查) taken in the 1950s and 1960s show that the average American was preoccupied with the questions "will I make a good living? "Will I be successful?" and "Will I raise successful, happy children?" Success was defined in terms of maintaining a stable family and "keeping up with the Jones". Most Americans believed that if they played by the rules--if they work hard and did what was expected, if they sacrificed their own needs to those of their family and their employer--they would be rewarded with an ever-increasing standard of living, a devoted spouse, and decent children. An expensive car, a suburban home, and children in college were tangible (可触知的) signs that hard work and self-sacrifice paid off.

单选题{{B}}Passage Three{{/B}}
Public speaking fills most people with
dread. Humiliation is the greatest fear; serf-exposure and failing to appeal to
the audience come a close second. Women hate it most, since girls are
pressurized from an early age to be concerned with appearances of all
kinds. Most people have plenty of insecurities, and this seems
like a situation that will bring them out. If parents, teachers or peers mocked
your foibles as a child, you fear a repeat. If you were under pressure to be
perfect, you are terrified of failing in the most public of ways.
While extroverts will feel less fear before the ordeal, it does not mean
they will necessarily do it better. Some very shy people manage to shine. In
fact, personality is not the best predictor of who does it well. Regardless of
what you are like in real life, the key seems to be to act yourself.
Actual acting, as in performing the scripted lines of a character other
than yourself, does not do the job. While politicians may limit damage by having
carefully rehearsed, written screeds to speak from, there is always a hidden
awareness among the audience that the words might not be true.
Although, as Earl Spencer proved at his sister Princess Diana's funeral,
it is possible both to prepare every word and to act naturally, as script rarely
works and it is used as a crutch by most people. But, being yourself doesn't
work either. If you spoke as if you were in your own kitchen, it would be too
authentic, too unaware of the need to communicate with an audience.
I remember going to see British psychiatrist RD Laing speak in public. He
behaved like a seriously odd person, talking off the top of his head. Although
he was talking about madness and he wrote on mental illness, he seemed to be
exhibiting rather than explaining it. The best psychological
place from which to speak is an unselfconscious self-consciousness, providing
the illusion of being natural. Studies suggest that this state of "flow", as
psychologists call it, is very satisfying. Whether in normal life or making
speeches, the key is to remind yourself that, contrary to what your teachers or
parents may have implied, your best is good enough. In the zone, a strange place
of authentic falsehood and shallow depth, play is
possible.
